It's hard to believe how the drone holds so steady in gusty wind. The wind was quite strong on the ridge especially at the spot where it was launched at the flat cut into the ridge for the U turn, at the exact beginning of this video, yet the drone hangs in air without being jostled. I asked Rob about that and he told me the drone communicates with eleven satellites to hold its place. That did not explain how the drone avoids moving even an inch. Not jostled around at all. No corrections show. Its blades must behave as gyroscopes holding it in place. The drone returns to its base when power becomes low. And it has a fine camera too. The launching spot is where the two baby rattlesnakes were spotted causing some excitement at the top.
